You are assuming these natives are just one tribe of a small number.
Cavemen always are. Of course, the episode could be taken to describe an unrealistic situation if we want to. But only if we want to.
And that Spock and the remaining four officers can hold them off with phasers
Five people with phasers always can. Of course, the episode could be taken to describe a situation atypical of Star Trek if we want to. But only if we want to.
fend off starvation by licking rocks
Starvation is rarely an issue for a group of healthy people, as long as they have warmth, shelter and water. The location provided water, the shuttle provided warmth and shelter.
Many survival stories get such things wrong. Our heroes faced barely any hardships at all, save for cavemen. And cavemen should be a known quantity when they so conveniently follow Earth patterns, with Folsom points and whatnot.
There was no escaping them on the planet and there could be an entire civilization of these beings. We don't know, so we go with what we're given, which is constant, imminent threat of death by giant creatures with greater strength and ferocity.
What we
really are given is three or four angry men throwing spears and rocks at strangers when the opportunity arises, and a supposed sighting of some more of the species. If these are cavemen, they should cease to be a threat simply enough - by killing a few of them.
Yes, you could suggest that Kirk could have left shuttles behind. But he didn't, he called everyone back. He also seemed to only have one more, the Columbus. Which was weird.
Not necessarily - the vulnerability of a shuttle was the reason for the emergency in the first place, so Kirk might hold back there. But it would be an option he would grow bolder with, given the initial success.
Sometimes playing it by ear is the right course of action. Staying on the planet would have cost lives. The script made no doubt of this.
Oh, I'm not in disagreement with that. I'm just saying that the script was implausible, and that all the implausibilities that manifested in the episode based on the script fell squarely on the shoulders of Spock who was making seemingly irrational decisions and finally triumphing against all reason. Which is weird, because Spock was supposed to be the rational guy.
That's neither here nor there, because the point is that a kill can make a body disappear, and predominantly does. That sometimes a corpse is left is actually a good thing for the argument, as it explains the battlefield in "Omega Glory".
Although as a side note, it would make sense for Lenore to kill her father with a phaser set on heavy stun, as supposedly unauthorized firings at stun settings do not trigger internal sensors, yet at kill settings they do. That is, they trigger an alarm in ST6, and if we interpret "Conscience of the King" this way, ST6 never really gets contradicted.
To kill Kirk that way, Lenore would have to walk right next to him and push the trigger a few times, which may well have been her plan; an initial shot from a distance would make things easier. But the frail Anton would die from a faraway stun shot, too.
Also, the Federation itself seems to be without a streak of institutional bigotry. They have (had) a starship crewed entirely by Vulcans.
The United States had all-black military formations at a time when institutional bigotry was in evidence - indeed, those formations
were the evidence!
Stiles stands out from the other officers and crew, which implies that his bigotry was an exception.
Or that each officer has his or her particular choice for hatred (such as with Chekov and Klingons), and Romulans were Stiles' hot button.
